5.1 新建 zabbix Mysql 数据库及专用账号
[usera@mysql ~] mysql -u root -p
mysql > CREATE DATABASE zabbix character set utf8 collate utf8_bin;
mysql > GRANT all ON zabbix.* TO 'zabbix'@'%' IDENTIFIED BY 'Password';
mysql > flush privileges;
mysql > quit
5.2 确认PHP可正常访问数据库
# /var/www/html/zabbix_connect_test.php
<?php
echo "Test db connection </br>";
$db_servername = "192.168.99.99";
$db_username = "zabbix";
$user_password = "Password";
$db_name = "zabbix";
$link = mysqli_connect($db_servername,$db_username,$user_password,$db_name);
if (!$link) {
die('Connect Error (' . mysqli_connect_errno() . ') '
. mysqli_connect_error());
}
echo 'Connected successfully' . mysqli_get_host_info($link) . "\n";
mysqli_close($link);
?>
# elinks --dump 127.0.0.1/zabbix_connect_test.php
Test db connectionConnected successfully 192.168.99.99 via TCP/IP
5.3 添加 Zabbix 软件仓库
# rpm -ivh http://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm

5.6 导入 Zabbix server 的初始数据库 schema 和数据
# scp /usr/share/doc/zabbix-server-mysql*/create.sql.gz usera@192.168.99.99:/tmp/
[root@Mysql tmp]# zcat /tmp/create.sql.gz | mysql -uzabbix -p zabbix
Enter password: ***********
确保导入成功，无报错!
5.7 配置数据库
# vi /etc/zabbix/zabbix_server.conf
DBHost=192.168.99.99
DBName=zabbix
DBUser=zabbix
DBPassword=Password
5.8 启动 Zabbix server 进程
# service zabbix-server start
# systemctl enable zabbix-server
默认LOG目录：/var/log/zabbix/zabbix_server.log
6 web UI 安装zabbix
重启一下Httpd 服务后
http://zabbix-server-ip/zabbix
初始登录密码： Admin / zabbix
7 其他
web ui 图形中文乱码
（注意备份原字体文件）
# yum install wqy-microhei-fonts
# cp /usr/share/fonts/wqy-microhei/wqy-microhei.ttc /usr/share/fonts/dejavu/DejaVuSans.ttf
zabbix agent 主被动
----------------------
主动 = agent active
被动 = agent
----------------------
主动与被动的说法均是相对于agent/proxy。
agent/proxy主动发送数据就是主动模式
agent/proxy等待server的请求，再发送数据就是被动模式。
主动模式可减轻Server压力监控项目很多就要把监控模式改为主动
----------------------
主动：ServerActive=ServerIP
agent请求server获取主动的监控项列表，并主动将监控项内需要检测的数据提交给server
server:10051 <-- agent
server(item) --> agent
server <-- agent(date)
----------------------
被动：Server ＝ ServerIP
server向agent请求获取监控项的数据，agent返回数据。
server(item) --> agent:10050
server <-- agent(date)
